These are the continuous thermal current ratings through the normally-closed trip contact — the contact that breaks the contactor coil circuit on overload. For a 400 V motor circuit, the 1 A rating at 400 V means the relay's auxiliary contact can safely interrupt the coil current of most contactors up to that size; the motor's full-load current is handled by the overload's own bimetal heater, not this contact. Power dissipation per pole is 1.9 W, so in a panel with multiple relays side-by-side, the cumulative heat rise stays manageable — no forced cooling required for typical layouts. The relay compensates for ambient temperature changes between -40 °C and +60 °C, keeping the trip curve accurate across the panel's operating range. Fastening is by direct contactor mounting — the relay clips onto the contactor's body, sharing the same DIN-rail footprint. No separate panel space or wiring between contactor and relay; the power connections pass through the relay's ring cable lug terminals (M3 screws for the main circuit). Dimensions are 45 mm wide, 76 mm high, 70 mm deep — a compact footprint that fits standard 45 mm wide contactor slots in the SIRIUS S00 frame. The auxiliary switch is integrated into the relay body, so no separate add-on block is needed for the trip indication.","metaTitle":"Siemens 3RU2116-1BJ0 SIRIUS Thermal Overload Relay, Size S00","metaDescription":"Siemens 3RU2116-1BJ0 SIRIUS thermal overload relay, Size S00, Trip Class 10, contactor mounting.
